Relative molecular weight：314.46Application guide：With sebacic acid and butanol as raw materials, esterification was carried out at about 140 DEG C under the catalysis of sulfuric acid. After the reaction was completed, neutralization and separation of water layers were carried out. Decoloration was carried out with activated carbon, and then the alcohol was removed and washed with hot water. Packaging materials used in contact with food, cold resistant, auxiliary plasticizer.Application example：
